That twat everyone wanted to murder in school due to his/her massively inflated ego, self-obsessiveness and downright sadism. Generally the bully, and often has repressed issues of their own, they are driven insane by the voices in their head telling them to be a conformist, and so drive everyone around them insane by doing the same thing, and yet ironically promotes himself/herself under the nebulous moniker of a "rebel". Murderer of self-worth, dignity, individualism and everything a modern society professes to stand for, yet promoted in the media and society in general as a great role model. Generally fails in life due to thinking they were too "cool" to get a job, or a house, or a source of income, and more often than not forced by terrible circumstances to work for the very nerds they were bullying. Listens to mediocre and downright bad pop music, and, assuming the pop to stand for popular, not populist, he/she forces his/her (lack of) taste onto other people. An all-round arrogant, sadistic tosser that should never have been let out of the asylum.
I don't need an example; you all know who I'm talking about. Make a stand, people; together, you can destroy pop culture, and be done with the cool kids forever!
